Those familiar with the older generation MINI Coopers, know the improvement they get from larger Rear Anti Sway Bars. It is the best way to improve your MINI, as far as car balance and Body Roll Management.

Front wheel drive cars, even the MINI Cooper, naturally understeer. The NM Engineering 25mm Rear Anti Sway Bar improves your F-chassis MINI by inducing more oversteer and increasing car handling predictability.

NM Engineering Anti Sway Bar features:

  • Mandrel Bent Solid Chromoly Bar- providing consistent diameter for precise torsion motion.
  • Forged Ends with two adjustment mounting holes.
  • Graphite Impregnated Urethane Bushing.
  • Glossy blue Powder Coat finish.
  • 25mm Heavy Wall Tube GT Rear Anti-Sway Bar is hollow for less weight and enhanced stiffness.

The two adjustment mounting holes provide 3 levels of stiffness:

  • stiff = both ends at forward holes
  • soft = both ends at rear holes
  • medium = one at forward and one at rear hole

MINI (2002-Current)

NM Engineering Billet Rear Sway Bar Clamp kit to replace factory PLASTIC clamps.  For use with the G3NMS2100 22mm Rear Anti-Sway Bar.

The kit features:

  • CNC machined 6061 billet aluminum clamps with military-spec hard anodized coating.
  • Graphite impregnated polyurethane bushings
  • Grease fittings

This kit provides strength improvements over the OEM plastic clamps and rubber bushings with the addition of servicing convenience. Also included in the kit are high grade mounting bolts and grease.

The clamps are engineered specifically for F-Chassis MINIs, unlike the cheap universal brackets with oblong mounting holes from other brands.

Those who used to, or still, own the older gen MINIs know how much of an improvement they get from 22mm Solid Rear Anti Sway Bar. It is essentially the best body roll management you can ever do to your MINI. The handling characteristic and steering input are so well enhanced it is almost as good, if not better, compared to installing lowering springs or coilovers.

Fits the following models:

2014-2022 F56 MINI Cooper and Cooper S Hardtop
2015-2022 F55 MINI Cooper and Cooper S Hardtop 4-Door
2016-2022 F57 MINI Cooper and Cooper S Convertible

Front wheel drive cars naturally understeer from the factory, even the MINIs. The NM Engineering Solid 22mm Rear Anti Sway Bar improves your F-chassis MINI by enducing more oversteer and increasing the car handling predictability.

NM Eng Anti Sway Bar features:

  • mandrel bent solid chromoly bar providing consistent diameter throughout for precise torsion motion
  • forged ends (not cheaply welded plate) with two adjustment mounting holes
  • graphite impregnated urethane bushing
  • glossy blue powder coat finish

Notes:

When ordering this sway bar, we Strongly recommend the G3NMS2105 Adjustable Drop Links (End Links) since the factory drop links are made from plastic and may not be up to the task with this performance sway bar upgrade.

Another option is the G3NMS2110 22mm Billet Sway Bar Brackets which are much more durable AND includes a zerk fitting to allow lubricating.

We at Mini Mania believe the rear anti-sway bar should be the first suspension upgrade on your MINI. Of course, we also recommend that you drive your MINI in a drivers education event before modifications to truly learn the characteristics of this fabulous car. Then you can appreciate the improvements you get from each of these upgrades.

Question:
I have seen in the MINI parts catalogue and this anti sway bar looks exactly like the one on the hybrid. But on ur page it says it doesn't fit. Are you sure?
Answer:
It is also a question of whether the bar will help, in addition to whether it will fit.
Can you measure the diameter of the rear sway bar on your hybrid? I suspect it is larger than the other F60 models due to the additional weight, so the G3NMS2115 may not be as effective.
